Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0 on NEW box

Question

I have looked at different solutions but nothing helped. Basically, i have a Kentico solution that came with MVC 3. I removed all the references and added MVC 5 via nuget. This works on the old test server since that has MVC 4 installed in it. We have deployed a new test web sever and this doesn't have MVC installed on it and we don't need it if DLLs are available in the bin folder. Now when i try to run the site on the new server, i get the following exception.

Could not load file or assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

I am confused as to why it is looking for MVC 3 when in my bin folder i have the MVC 5 DLL available.

What reference am i missing here? The only thing that is coming to my mind is that i am missing some dependent assembly.

Answer 1

It could be a reference in a different project or config. Search for 3.0.0 see what comes up. NuGet package installs can be tricky. You know something is looking for it, you need to let it know you've upgraded.
